Answer:

r=3

y=3x

Step-by-step explanation:

We are given that a graph.

The graph shows  a proportional relationship between x and y.

From given graph  we can see that when x increases then y is also increases.

Therefore, y\propto x

y=rx

Where r=proportionality constant

x=5 and y=15

Substitute the values then we get

15=r(5)

r=\frac{15}{5}=3

Substitute the value of r

Then, the equation to represent the relationship is given by

y=3x

The constant of proportionality (r) appears to be 3.

y = 3x . . . . . . . x = number of tickets sold; y = dollars collected

Why does these expressions 2(30x-24), 3(20x-16), and 4(15x-12) have the same expansion?
MariettaO [177]
The expressions have the same expansion I'd say because the pairs 2 and 30, 3 and 20, and 4 and 15 because they are all equivalent to 60 because they are all factors of 60.

Same goes with the other pairs, because they are all equivalent to 48 because they are all factors of 48.

When sample size increases Group of answer choices
Olenka [21]

Answer:

Option A)

Confidence interval decreases

Step-by-step explanation:

If we increase the sample size, then,

  • The standard error of the interval decrease.
  • If the standard error increase, the margin of error of the interval decrease.
  • If the margin of error decreases, the width of the confidence level decreases, hence, the confidence interval become narrower.

Thus, the correct answer is

Option A)

Confidence interval decreases
